This also happened:
Typed "import" into goto box but wasn't allowed to create it. So i changed the name right in the same New Card page to allow creation of card called import, and when i saved it that ticket was created, but it hung all the plus cards off of a new import card -- import+status, etc.
Also see allow creation of card called import
May be related to Cardtypes names matching existing ruby modules fail on new. In that there is a ruby module named "Import" (doesn't have to be cardtype to cause problem?)
